Answer:
value of n = 2
Step-by-step explanation:

We need to solve the above equation.
Find Least Common multiplier from 5n, 5 = 5n
Multiply both sides of the equation by 5n

Now finding the value of n.
Adding -4 on both sides

Multiplying both sides by -1
n = 2
The value of n is 2.
We can verify by putting value of n in the given question.

So, value of n = 2
It's a. 3.
because
3+6x=21
6x=18
x=3.
